The GM25-1 is a portable CO2 detector for air quality in confined spaces. It measures elevated levels of CO2 and reduced levels of O2 by analysing the ambient air within the space.
Designed to be both lightweight and portable, the GM25-1 CO2 analyser is used worldwide for security operations and indoor activities. Operation is extremely simple, yet the readings obtained are comprehensive and accurate.
The GM25 series can be used by itself or in combination with the DataField GM25 Connect app which allows the GM25 analyser to be controlled via a mobile device or tablet. This results in faster operations whilst being able to configure how readings are taken suiting the individual users needs.

The GM25-1 can be used for stowaway detection as well as CO2 Analysis in a variety of different sectors, including:
The GM25 series can be used by itself or in combination with the DataField GM25 Connect app which allows the GM25 analyser to be controlled via a mobile device or tablet.
This results in faster operations whilst being able to configure how readings are taken suiting the individual users needs. If an internet connection is present, the application can live-stream the data to the web-based portal as opposed to downloading it directly from the device after all readings have been taken, resulting in much faster access to the gas analysis data.

The GM25-1 is a portable low-level CO2 analyser. Using an NDIR sensor it picks up CO2 concentrations in a given space up to 10,000ppm.
Before enquiring about the GM25-1, please do take a look at the instrument datasheet to view all the available expansions. The GM25-1 includes the option to include an Oxygen 0-25% sensor. When placing your enquiry, do mention whether the Oxygen expansion is required as this will factor into the final cost and lead time.
The most popular application for the GM25-1 is within the security sector. The sensitivity of the NDIR sensor is such that it can pick up slight changes in CO2 levels within an enclosed space, indicating a human presence. This product can also be used to measure the ventilation within a room, such as an office space.
When purchased, you will receive the following with the GM25-1:
The sample pipe provided is ~1m in length and includes a dust trap filter to prevent particulates entering the sensor and causing damage. Gas Data also have available external attachments for the GM25-1:- 1m Lance Probe- Under door needle probe. Attach your desired sample pipe or accessory to the inlet manifold and scroll to the sample screen. The pump will run automatically, and you will see the CO2 levels on the screen.
The GM25-1 requires annual service and calibration. Please contact your supplier to organise service in good time prior to the calibration date- shown on the latest calibration certificate and on the home screen of the instrument.
Identify the part you require and contact the distribution partner from whom you purchased the analyser. Alternatively, visit the Gas Data website and fill in the enquiry form associated with consumables and spares.
